SPECIFICATION forirning part of Letters Patent No. 734,507, dated July 28, 1903.

Serial No. 112,201. (No model.)

To all whom it may concern:

Be it known that I, GILBERTF. BURTOH, a citizen of the United States, residing at Onida, in the county of Sully andState-of South Dakota, have invented certain new and useful Improvements in Sulky Attachments for Harrows; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,-reference being had to the .accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to a sulky attachment for harrows; and its object is to provide a wheeled carriage to support the driver and the rear end of the frame so constructed and arranged in relation to the seat and the draftbar of the harrow that the weight of the driver may counterbalance the weight of the frame and its carriage, and thereby tend to lift the front of the harrow from the ground, so as to.

pivotally mount the same on the cross-bar of the reach, so as toassist in carrying out the above-mentioned objects.

Other objects and advantages will appear asthe nature of the invention is better understood from the following description and the accompanying drawings, in which-.

Figure 1 is a plan View of my attachment Fig. 2 is a side elevation of the same with the carriage shown in dotted lines as turned around to reduce the leverage action of the reach-bars. Fig. 3 is an end elevation of the carriage and the cross-bar of the reach. Fig. 4 is a vertical section on the line w 00 of Fig. 3 with the seat adjusted to a position in front of the carriage. The harrows 1 may be of any preferred construction and are attached in any suitable manner to the draft-bar 2, which is provided with draft connections 3.

the latter having a turnbuckle 9 to take up any looseness. I

The cross-head 6 is composed of a lower plate 10 and an upper plate 11, bent downwardly at its ends to engage the lower plate to provide a space therebetween for an oilcup 12. The reach-bars are secured to the upper plate, while the lower plate providesa bearing for the top of the frame of the carriage, hereinafter to be described.

The diagonal braces 13 are secured at their forward ends to the reach-bars and at their rear ends to the plate 10 of the cross-head and are bent upwardly and forwardly across the same to provide footrests 1.4 for the driver. Brace-rods 15 are also attached to each end of the lower plate of the cross-head and extend into engagement with the draftbar 2 to serve as supplemental reach-bars.

The carriage consists of a frame 16, having an upper bearing-face 17, depending parallel forks 18, which are bent outwardly at right angles, as at 19, and then curved upward and inwardly and [secured to. the upper portion of the forks to provide braces 20 for the horizontal right-angular portion 19. A carryingwheel 21 is journaled in suitable bearings 22 between the forks 18. Secured to the horizontal right-angular portions on each side of the carrying-wheel 21 are depending arms 23, between which are mounted auxiliary supporting-wheels 24:.

A kin g-bolt 25 is rigidly secured in the horizontal bearing-face of the carriage-frame and extends through the cross-head and the seat-supportin g bar 26. This seat-bar is provided with an aperture 27 to be engaged by the stud 28 in the end of the reach-bars, as shown in Fig. 2, and when in this position the weight of the driver will counterbalance the weight of the draft-bar and tend tolift the front of the harrows from the ground, so that the front row of barrow-teeth will only scrape the soil, while each succeeding row of teeth will enter the ground at a greater depth. In order to regulate this lifting leverage or counterbalancing action, the upper bent end 29 of the seat-bar is provided with a longitudinal slot 30, in which a stud 31, fastened to the seat 32, slides. The seat-bar is rotatable on the king-bolt 25, so that the seat may be turned to a position in front of the carriage, as shown in Fig. 4, and when in such position the weight of the driver will press the draft-bar 2 down and cause the front teeth of the harrows to engage the soil at a greater depth.

On the lower plate 10 of the cross-head are formed integral downwardly-bent lugs 33, which extend in the path of the bearing-face 7 of the carriage-frame and serve as stops to limit the rotatable movement of the carriage. \Vhen it is desired to turn the carriage to the position shown in dotted lines in Fig. 2, the nut on the end of the king-bolt is loosened to permit the cross-head to be lifted, so that the bearing-face 17 of the carriage will clear the stops 33, and when thus adjusted the leverage action of the reach-bars is reduced.

Having thus described my invention, what Iclaim, and desire to secure by Letters Patent, is-

1. Asulkyattachmentforharrows comprising a pair of reach-bars adapted to connect with the draft-bar of the harrows, a crosshead, a carriage-frame pivotally connected with the cross-head, and a reversible and adjustable seat adapted to be extended in the rear of the carriage or projected in front of the same.

2. Asulky attachment forharrows comprising a pair of reach-bars connected with the draft-bar of the harrows, a cross-head, a carriage frame pivotally connected with the cross-head, and supplemental reach-bars connecting the ends of the cross-head and the draft-bar.

3. A sulky attachment forharrows comprising a pair of converging, arched reach-bars, a cross-head composed of an upper and lower plate spaced apart, diagonal braces connecting the reach-bars and the lower plate of the cross-head and extended over the latter to provide foot-rests, and a carriage pivoted to the cross-head and adapted to be turned to assume difierent angles with relation to the reach-bars.

4. In a sulky attachment for harrows, the combination with the reach-bars having a cross head composed of upper and lower plates spaced apart, of a carriage pivoted to the cross-head and composed of a frame having a horizontal bearing-face, depending parallel forks which are bent outwardly at right angles and then upwardly to engage the forks, arms depending from the right-angular bent portion, and supporting-wheels mounted between the forks and the depending arms.

5. In a sulky attachment for harrows, the combination with the reach-bars having a cross-head, of a carriage-frame pivoted to the cross-head and having ahorizontal bearingface for the cross-head, and stops on the crosshead to be engaged by the horizontal bearingface to limit the rotatable movement of the carriage.

6. In a device of the class described, the combination of the reach-bars having a crosshead a reversible and adjustable seat mounted on the reach-bars, a carriage swiveled to the cross-head and adapted to be turned to assume different angles with relation to the reach-bars.

In testimony whereof I affix my signature in presence of two witnesses.
